Thanks for reply. I think I already made a crossover cable : pins 1,2,4,5 and 4,5,1,2 and I still see red light on modem.
pin 1 is in rj45-1 and is going to pin 4 in rj45-2 (orange with white stripe) pin 2 is in rj45-1 and is going to pin 5 in rj45-2 (solid orange) pin 4 is in rj45-1 and is going to pin 1 in rj45-2 (solid blue) pin 5 is in rj45-1 and is going to pin 2 in rj45-2 (blue with white stripe) Does color of wires matter ? I showed a cable to telco workers when they mount isn pri modem and they said its ok. I dunno what is the problem. When I put loopback in modem's port I still see red lights on rx. I know alarm should fall on their side and I need to see no red lights right ? Can you tell me is libtermcap package essential for compiling libpri or zaptel ? I installed all packages except that because there is no such package on Ubuntu 8.04. Maybe libpri or zaptel did not compile ok because they could not find libtermcap ? I din't see any error massages and both said compiled and installed succesfuly. Maybe those lazy telco workers even did not activate number who knows everything is possible.
